Justification:
This European endemic was formerly found in Belgium, Luxembourg and France, but is now extinct in the wild. The species was growing within fields of Spelt Wheat (Triticum spelta) and was re-sown each year with the wheat seeds. As Spelt Wheat is no longer agriculturally planted, Bromus bromoideus went extinct throughout its former range. It still persists in collections of some botanic gardens.

This European endemic was formerly found in Belgium, Luxembourg and France, but is now extinct in the wild. It is in cultivation in the Botanic Garden of Liège (Buord and Lesouëf 2006) and Brest. Its centre of distribution was found in southeast Belgium, just extending into France and Luxembourg (therefore its common name "Ardennes Brome") (Morgan and Leon 1992). It might also have been introduced to western Germany, the Netherlands and the UK (Morgan and Leon 1992).

The species was originally growing within fields of Spelt Wheat (Triticum spelta). The growth patterns and the seed size closely match harvesting time and seed size of Spelt Wheat and thus it was re-sown each year with the wheat seeds. As Spelt Wheat is no longer agriculturally planted, Bromus bromoideus went extinct throughout its former range (Morgan and Leon 1992).
